mechanisms of prior constructions, in which the setting-die is separate from the punch, I

`prefer to mount-the setting-die in the path of movement of the punch, so as to be displaced by the punch duringits feeding movement and to return to sett-ing position between its cooperating die and the punch when the punch rises after having fed the material.

While my invention in its broadest aspects is not limited to the constructions above referred to, I consider such constructions of value as embodyingmy invention in an eicient and simple machine and in the best form at present known to me; and certain features of my invention consist in providing a machine, comprising a punch acting to feed the material With the devices and combinations of devices hereinafter described and claimed, possessing the advantages above set forth and other advantages which will be apparent from the description hereinafter contained.

While a machine embodying the features of my invention above referred to may be provided with any suitable form of die as affordin;r a simple and compact construction, I prefer to employ a divided setting-die, and this die I consider a feature of 'my invention.

A preferred form of my invention is illustrated in the accompanying drawings, in which- Figure lisa View in side elevation of au eyeleting-machine embodying the same, the mechanism for feeding the eyelets being omitted, said machine being the same in all essential particulars, except as modified inaccordance with my invention, as the well-known Hawkins eyeleting-machine. Fig. 2 is a View in front 'elevation of the machine shown in Fig. 1. Fig. 3 is a view in rear elevation, a portion of the machine-frame being broken Fig. `4 is' a plan view of the work-supporting table, the presser-foot, the setting-die, and the means for supporting the die on the frame of the machine. Fig. 5 is a sectional view on the lne 5 5 of Fig. 4, and Fig. 6 is an underneath plan view of the setting-'die and the means for yieldingly holding the die in setting position. j

Referring to the drawings, 1 indicates the frame of the machine, in the lower portion of which is journaled the driving-shaft 2, provided with the driving-pulley 3. In suitable bearings in the front portion of the machineframe is mounted a vertically-reciprocating rod 4, which carries at its upperend a die 5,

which cooperates with the setting-die in setting the eyelets, as will be hereinafter described. The rod 4 is reciprocated from the shaft 2 by means of a disk`6, secured to the 'roasts front end o'f the shaft 2, on which is pivotally mounted a block 7, which is received in a transverse slot in the rod 4.

8 designates a lever pivoted at the upper end of a rod 9, swivelingly mounted in the upper portion of the machine-frame. A nut 10 is screwed on the lower end of the rod 9, and between the nut and the frame a coiled spring 11`is interposed. The rear end of the lever 8 extends through a slot in a yoke 12, carried at the upper end of a vertically-reciprocating rod 13, which reciprocates in guideways formed in the machine -frame. The lower end of the rod 13 is provided with `a cam-roll which engages a cam-groove 14,

out in the rear face of acam-disk 15, secured to the shaft 2. As shown .in the drawings, the cam-roll does not t the cam-groove 14 accurately throughout the revolution of the cam-disk, and in order to keep the roll in contact with the inner edge of the cam-groove a coiled spring 16 is provided, which at its upper end is connected to the yoke 12 and at its lower end to the frame of the machine. By cutting the outer edge of the cam-groove 14 to correspond with the inner edge it will be evident that the spring 16 could be omitted. By means of the cam-groove 14 and the reciprocating rod 13 vertical. oscillating movements are imparted to the lever 8.

A lever 17 is pivoted to the machine-frame, the lower end of which is provided with a cam-roll which engages a cam-groove cut in the front face of the cam-disk 15 and the upper end of which bears against a screw 18, projecting laterally from the rear end of lever 8. The upper end of the lever 17 is provided with a lateral extension 19, which is connected to the rear end of lever 8 by means of a coiled spring 20. Passing through one end of the yoke 12 is a screw 21, which forms an IOO adjustable stop for limiting the lateral movement of the lever 8 in one direction. By means of the lever 17 the lever 8 is swung laterally, the rod 9, to the upper end of which the lever 8 is pivoted, turning in its bearings. The spring 20 tends to hold the screw 18 of the lever 8 in contact with the upper end ot' the lever 17, but permits the lever to move away from the screw when the lever contacts with the adjustable stop 2l. By means of the screws 18 and`21 the lateral throw of the lever '8 can be varied as desired.

The mechanism so far described, with the exception of the shape of the cam-groove 14, is the same as that of the well-known Hawkins eyeleting-machine. In the Hawkins machine the setting-die is carried at the front end of the lever 8 and is actuated by the lever to enter the hole previously punched in the material by a separat-e punchand feed the material into a position to bring the hole directly over the lower die 5.

In order to utilize the mechanism above described in carrying out my invention, I mount the punch'in the front end of the lever 8, the punch being indicated at 22. The

IIO

cam-groove 14 is shaped to impart to the punch 22 a downward movement to punch a hole in the material and thereafter to slightly raise the same to clear the work-supporting table without withdrawing it from the material. The punch is then swung to the left, as viewed in Fig. 2, to feed the material to bring the hole punched therein directly over the lower die 5 and in line with the lower die and the setting-die when the setting-die is in settin g position-that is, when the setting-die is in line with the lower die. It is necessary that the setting-die should be in close proximity to the surface of the work when in position to coperate with the lower die in setting the eyelet. When in this position, however, the die is in the path of movement of the punch, and in order to allow the punch to properly feed the material I mount the setting-die so that it can be displaced by the punch during its feeding movement and be returned to setting position when the punch rises after having fed the material. The construction which I prefer for so mounting the setting-die is clearly shown in Figs. 4, 5, and 6. In these figures, 23 designates the setting-die. This die is annular, as is necessary in this class of machines, in order to set the eyelets and is divided longitudinally or in the direction of its axis into two parts, each of which is secured to or formed integral with a lever 24E, pivotally mounted at 25 on a block 26, which is supported at a suitable distance above the worksupporting table 27 by means of a sleeve 28, which rests upon a portion of the machine-frame. The block 26 and the sleeve 28 are held in position by a headed bolt 29, which passes down through the block and sleeve and screws into the machine-frame. The parts of the divided die 23 are yieldingly held in contact in setting position by means of a coiled spring 30, connecting the levers 24, the correct position of the die being insured by suitable stop-pins 24a, which limit the movements of the levers. The ends of the levers 24, which extend toward the punch 22, are beveled to form a notch into which the punch passes during the feeding movement. The punch first passes into the notch and then separates the levers, thereby displacing the die 23 from its setting position. The lower end of the punch is reduced in diameter, as shown, to form a shoulder. As the punch rises from the` lower dotted line position shown in Fig. 5 to the upper dotted-line position the parts of the divided die 23 are brought into contact by the action of spring 30, the levers 24 being cut away above the die 23 to allow this movement. When the parts of the die have thus been brought into contact, the upper surface of the levers 24 rest against the shoulder of the punch 22, which thus forms au abutment for the levers and securely holds the setting-die from upward displacement during the setting operation. For guiding the work during the feeding opera-' tion an adjustable guide 3l is secured to the upper surface of the table 27, and for hold ing the work upon the table a presser-foot 32 is provided. This presser-foot is secured to the upper end of a vertical rod 33, mounted to slide in bearings in the machine-frame. The presser-foot is normally pressed against the work by means of a coiled spring 34, surrounding the rod 33 and interposed between the upper bearing for the rod and au adjustable collar 35, secured to the rod. The lower end of the rod 33 rests upon one arm of a three-armed lever 36. One arm of this lever is connected by means of a rod 37 to a foottreadle, by means of which the presser-foot can be raised by the operator to allow the iusertion and removal of work. For raising the pressure-foot automatically during the feeding movement of the punch a block 38 is secured to the shaft 2 and provided with a roll 39, which is arranged to contact with the third arm of the three-armed lever 36.

The operation of the machine above dein the position shown in Fig. 2 the lever 8 is actuated to cause the punch to descend into contact with the work-supporting table or a suitable cutting-block secured thereto and punch a hole in the material. The lever 8 is then actuated to raise the punch slightly and then move the punch to the left as viewed in Fig. 2, tothe lower dotted-line position shown in Fig. 5. During this movement the parts of the divided setting-die are separated to allow the 'punch to bring the hole formed thereby directly over the lower die and in alinement with said die and the setting-die when the setting-die is in setting position. The lever 8 is then actuated to raise the punch to the upper dotted-line position shown in Fig. 5, which allows the parts of the settingdie to return to setting position. The lower die is then raised, carrying the eyelet supported thereon through the hole in the material against the setting-die, which is pre-4 vented from upward displacement during the setting operation by the engagement of the upper surface of the levers 24 with the abutment formed by the shoulder of the punch. After the eyelet is set the parts are returned to the position shown in Fig. 2.

It is to be noted that the displacement of the setting-die is effected by the portion o f the punch above the shoulder, and as this IOO IAIO
